IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 1 81,865, dated September 5, 1876 application filed Ju1y'31, 1876.

To all whom it may concern Be it known that I, JAMES PEIRCE, of Nora, Jo Daviess county, Illinois, have invented a new and Improved Com bined Door-Check and Bnfl'er, of which the following is a specification:

Figure l is a plan of a door in section, showing the manner of attaching my improvement; and Figs. 2 and 3 are detail views of the attachment.

Similar letters of reference indicate corresponding parts.

My invention consists in the novel construction and arrangement of a spring-latch attached to the base-board or wall, combined with a catch and bufi'er that is attached to the door, so arranged that it may act as a latch and buffer combined, or as a latch alone.

A is a latch, that is pivoted to the back piece a, and swings between two curved braces, 19 b. c c are stop-pins, that limit the motion of the latch up and down. A spring, d, rests on the support 6, and presses the latch A upward. The spring d is held in place by a pin,f, that passes through both the latch A and support a. The back piece a is attached to a beveled .ent

block on the base-board or wall. g is a frame containing a piece of rubber, h, and having the catch 2? attached to the door in such a positiouthat the latch A will engage'with the catch i as the door is opened. If the door is opened forcibly, the rubber it acts as a buffer and prevents concussion. If it is desired to use the device as a buffer alone, the pin f is withdrawn, and the spring cl is removed, when the latch A will rest on the lower pin 0, and is incapable of engaging with the catch *5, but may act, in connection with the rubber h, as a buffer.

Having thus described myinvention, I claim as new and desire to secure by Letters Pat- A door-check provided with latch A, pins of, spring (1, and frame g, the latter having spring h and catch i, the spring (1 and pin f being removable, as and for the purpose specificd.

JAMES PEIROE.
